Description

A drying device for solar backplane film production

technical field

The utility model relates to a drying device for solar backboard film production.

Background technique

With the gradual reduction of non-renewable energy and various pollution problems caused by the production and use of mineral resources, countries are using policy and legal means to gradually increase the development and utilization of renewable energy and clean energy, and strive to improve Its share of total energy use. Among these clean and renewable energy sources, solar energy is one of the most important energy sources. Solar panels are commonly used in solar equipment at present, which is an important device for converting solar energy into electrical energy. The service life of such products is generally designed for more than 25 years. To ensure that the product reaches such a long service life, it is necessary to strictly control the quality of each component, and the role of the solar module packaging backplane in these components cannot be underestimated. The plate film plays the role of protecting the cells in the photovoltaic module, and needs to have reliable insulation, water resistance, and aging resistance. In the drying process of the solar backplane film production process, the hot air is generally sent to the drying room for drying, and then the gas is discharged from the exhaust pipe, but because the discharged gas still has a certain amount of heat, waste directly.

Utility model content

The purpose of the utility model is to provide a drying device for solar backboard film production, which has a reasonable structure, can effectively dry the solar backboard film, and can reduce waste of resources.

In order to achieve the above purpose, the technical solution of the utility model is to design a drying device for solar backplane film production, including a frame, a drying box fixed on the frame, and a circulating air duct connected to the drying box; The top of the drying box is provided with an air outlet, and the bottom of the drying box is provided with an air outlet. The two ends of the circulating air pipe are connected with the air outlet and the air outlet respectively. and the heating jacket between the air outlet; the side of the drying box is provided with an inlet and outlet for the solar backplane film to pass through, and the drying box is provided with a plurality of horizontally arranged guide rollers and hot air conveyers located above the guide rollers. The hot air conveying pipe is parallel to the guide rod, the hot air conveying pipe communicates with the air outlet, and the hot air conveying pipe is provided with a plurality of downward blowing holes. By adopting the above solution, the film of the solar back panel can be effectively dried, and the waste of resources can be reduced.

Preferably, the circulating air duct is provided with a dust filter located between the exhaust fan and the air outlet. Remove dust from the air by adopting the above solutions.

Preferably, a temperature sensor is provided inside the drying box, and a digital display connected to the temperature sensor is provided on the outer wall of the drying box. By adopting the above solution, the digital display meter can display the temperature in the drying box in real time, which is convenient for real-time adjustment of the temperature in the drying box.

Preferably, an insulation layer is provided on the inner wall of the drying box. By adopting the above solution, the insulation layer can effectively reduce the heat in the drying box from being emitted to the outside, thereby helping to reduce energy consumption and achieve the effect of energy saving and emission reduction.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

The technical scheme of the concrete implementation of the utility model is:

As shown in Figure 1, a kind of drying device for solar backplane film production comprises frame and the drying box 1 that is fixed on the frame, and the circulation air duct 2 that is connected to drying box 1; The top of the box 1 is provided with an air outlet 3, the bottom of the drying box 1 is provided with an air outlet 4, and the two ends of the circulating air pipe 2 are respectively connected with the air outlet 3 and the air outlet 4, and the circulating air pipe 2 is provided with an exhaust fan 5 and a heating jacket 6 located between the exhaust fan 5 and the air outlet 3; the side of the drying box 1 is provided with an inlet and outlet for the solar backboard film 7 to penetrate, and the drying box 1 is provided with a plurality of horizontally arranged The guide roller 8 and the hot air conveying pipe 9 above the guide roller 8, the hot air conveying pipe 9 is parallel to the guide roller 8, the hot air conveying pipe 9 communicates with the air outlet 3, and the hot air conveying pipe 9 is provided with a plurality of Downward blowing holes.

Moreover, the above-mentioned circulating air duct 2 is provided with a dust filter 10 located between the exhaust fan 5 and the air outlet 4 .

In addition, a temperature sensor 11 is provided inside the drying box 1 , and a digital display meter 12 connected to the temperature sensor 11 is provided on the outer wall of the drying box 1 .

An insulating layer is provided on the inner wall of the above-mentioned drying box 1 .

During work, the solar backboard film 7 is conducted by the guide rod 8; The 6 sections of the heating jacket are heated, and the heated air is transported to the hot air delivery pipe 9, and blown to the solar backboard film 7 through the blowing holes, thereby drying the solar backboard film 7. The air extracted from the drying box 1 still has a certain amount of heat, which is heated by the heating jacket 6 and then transported to the drying box 1 for use. Such circulation can reduce waste of resources.
